Isu Station tonkatsu with kake udon add-on, packed to go: Kosi
Kosi Isu Branch is a handmade udon and tonkatsu restaurant about 200m from Exit 9 of Isu Station in Dongjak, Seoul. Visiting on a weekday evening, the writer ordered tonkatsu with kake udon added, plus toriten bukkake udon with extra tonkatsu — so much food that the leftover tonkatsu had to be packed to go. A great spot to try both hot and cold udon in one sitting by pairing a single dish with a side.
